computer is a machine that manipulates data according to a list of instructions.
The first devices that resemble modern computers date to the mid-20th century (1940–1945), although the computer concept and various machines similar to computers existed earlier. Early electronic computers were the size of a large room, consuming as much power as several hundred modern personal computers(PC).[1] Modern computers are based on tiny integrated circuits and are millions to billions of times more capable while occupying a fraction of the space.[2] Today, simple computers may be made small enough to fit into a wristwatch and be powered from a watch battery. Personal computers, in various forms, are icons of the Information Age and are what most people think of as "a computer"; however, the most common form of computer in use today is the embedded computer. Embedded computers are small, simple devices that are used to control other devices — for example, they may be found in machines ranging from fighter aircraft to industrial robots, digital cameras, and children's toys.

第一个设备,像现代计算机日期到20世纪中叶(1940 - 1945),尽管计算机概念和各种设备类似电脑以前。早期的电子计算机是一个大房间的大小,消耗更多的能源为几百现代个人电脑(PC)。[1]现代电脑都基于微型集成电路和有数百万到数十亿倍,更有能力,同时占用空间的一小部分。[2]今天,简单的电脑可以小到足以放进一个手表和从一个手表电池供电。个人电脑,以不同的形式,是信息时代的象征,是很多人认为的“电脑”;然而,最常见的计算机在使用今天是嵌入式计算机。嵌入式电脑虽小,简单的设备,用于控制其他设备——例如,它们可能被发现
